MEANS FOR LUBRICATING LINOLEUM-DIE MECHANISMS.

Application filed November To all whom t may concern:

Be it known that I, JOHN TAMBERLIN, a citizen of the United States, residing in the city of Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented certain Improvements in Means for Lubricating Linoleum-Die Mechanisms, of which the following is a specification.

My invention is designed to provide means for automatically lubricating sur faces of an inlaid linoleum machine with which sheeted, linoleum composition contacts in the operations of translating and punching it, for the purpose of preventing the linoleum composition from sticking to said surfaces.

The improvements are particularly adapted for application to inlaid linoleum machines having pattern plates in which tesserae are deposited by reciprocating cutting dies an-d stripper plates for disengaging the punched sheets from the dies, the tesserae being carried by such pattern pla-tes into position to be deposited on the backing material.

In its Apreferred form, my improvements comprise a lubricant distributor fed from a fount which is movable vertically with dies and stripper plate to supply the lubricant, the distributor being movable with the pattern plate carriage over the dies and stripper plate, and a second lubricant distributor and fount for feeding the same, which are carried by the machine frame and over which the pattern plate is movable.

The drawing is a broken sectional view showing part of a linoleum machine having my improvements applied thereto.

The mechanism illustrated comprises the frame members 1 to which the head 2 is fixed by the tie rods 3. A reciprocable block 4, having thereon the dies 5 and stripper plate 6 supported by the springs 7, is carried through the bearings 3 by the revoluble cams 9 fixe-d on the journalled shafts 10, the latter being driven and revolved in unison by the meshing spur wheels 11 fixed thereon.

A die plate 12 is carried by a carriage 13 comprising the rack bars 14 movable on the Ways 15, the plate being suspended from the frame by the hangers 1G having a limited movement therein.

It will be understood that, when a sheet 2, 1920. Serial No. 421,279.

is placed between the plates 6 and 12 in the l in the die plate as its upward movement is stopped by its engagement with the carriage 13, this plate with the shapes therein falling a limited distance as the block recedes and the stripper plate rises relatively to the dies to clear them of the punched sheet.

A lever 17, fulcrumed in a hanging bearing 18, is provided at one end with a weight 19 and at the other with a roller 2O which is held by the weight in engagement with the cam 21 fixed to and revolved by one of the shafts'lO. The lever 17 has a link 22 pivotally connected thereto, at one end thereof, concentrically with the roller 20, the other end of the link being pivotally connected to a lever 23 having the fulcrum 24 on the frame.

The free end of the lever 23 is pivotally connected to one end of a link 24 which has its opposite end pivotally connected to a gear quadrant 25, the quadrant having the counterweight 26 and being fulcrumed on the bearing 27.

The quadrant 25, oscillated by the revolving cam 21 through the intermediate links and levers described, engages and rocks a spur wheel 28 journalled by means of a shaft 29 and having spur wheels 30 fixed thereto. A wheel 30 drives a gear wheel 31 journalled by means of a shaft 32 and the wheels 30 reciprocate the rack bars 14 on the ways 15.

The shaft 32 carries a sprocket wheel 33 which is revolved by the wheel 31 to which it is fixed, the sprocket wheel driving a chain 35 which passes over and drives a sprocket wheel 36 fixed on a journalled shaft 37. This shaft is provided with the sprocket wheels 38 and the friction drum 39, the former driving the chains 40 and the latter carrying the punched sheet.

The chains 40 pass under the idler sprocket wheels 41 and over the sprocket wheels 42 which are fixed to and revolve the friction drum 43 carried by the shaft 44 and carrying the sheet 45 to be punched.

The nipper bars 46 and 47, movable with the chains 40, engage the sheet 45 and carry it through the mechanism above the dies 5 and stripper plate 6A and? beneath the'. die Dlate'12.

The lower nipper 47 has a strip 48, such as felt, fixed to andV depending therefroinso that it will sweep over the.y dies la and the plate 6 in the lowered position thereof, as the wheels 30 advance the racks 14 and the nipper bars 46 and 47 draw the sheet 45' over these parts 5 and 6 and under the die plate 12, the felt having been saturatedwith a lubricant in the fount 44 carried by the bloc'ki 4 as the latter risesand applying the same to" the top surfaces of the parts 5 and' 6 in the rearward as well as the forward movement of the' carriage 18.

A fount- 49v supported by a bearing 50'; on the frame 1 i's provided with a wiper 51, suitably of felt, which is carried by a rod 52' so' that its lower part dips into a lubricant iin the' fount and its upper part will Contact with the bottom of the die plate 12 as it reciprocates thereover, the wiper being adapted' by the rod to: be rocked a limited distance by the contact of the plate therew'it'li.4 Consequently, the bottom of the die platey is kept lubricated by the wiping action of the lubricating device 51 through which the lubricant is carried by capillary action.

Having describedl my invention, I claim:

1.- In a machine of the character described, the combination with linoleuml cutting mechanism and linoleumv translating mechanism, of means comprising a lubricant font movable by one of said mechanisms and a wiper movable by the other of said mechanisms independently of said font for' lubricating partsl of said machine contacting with material cut thereby.`

2. In a machine of the character described, the" combination with ts'serae cutting and translating mechanisms comprising vertically reciprocating dies provided with a stripper plate and a transversely movable die plate, of lubricating means comprising a Wiper movable with said die plate over said dies and stripper plate.

3'. Inmachine of thecharacter described, the combination With tesserae cutting" translating mechanisms comprising dies and a movable die plate, of a lubricant distributor carried by the translating mechanism over said die'sand a second lubricant distribi'itor over which said die platev is movable.

I In a machine of the character described, the combination With a reciprocating carriage' and a die plate carried thereby, of,` a lubricant distributor connected with said carriage, reciprocating punching mechanism in Contact with which said distribut'ior is' movable by saidpcarria'ge, and a fount connected' with and reciprocated by said pirn'ch'ing mechanism for supplying a lubri'c'airt'v to said distributor.

5. a machine of the character de'- scribed, the combination with vertically reciprocating dies and a stripper plate therefor, of a reciprocating' carriage anda die plate carried tl'iereby, a' lubricant distrib'- utor movable with ysaid carriage over said di'e's and vstripper plate', a lubricant distributor the path of and laclapt'edto apply a lubricant to said die plate, and' reservoirs for feeding lubricant to saidV distributors'.
